<br />W <br />t- <br />.... <br />t- <br /> <br />Plan One - Continuation of Ongoing Programs <br /> <br />This alternative plan assumes continuation of ongoing conservation <br />programs_ Lando~ners in the valley are presently applying conservation land <br />treatment. Some treatment 15 applied by individuals on land under their control <br />while other practices arc implemented by groups of lando~ners for mutual benefit. <br />Rates of implementatIon are influenced by the amount of funds available through <br />government cost share and technical aSSIstance programs, the practices eligible <br />for government assistance, and the fInancial resources of landowners to install <br />irrigation improvements. Application of soil and water conservation measures <br />is expected to contInue ~hether or not an accelerated program for salinity <br />control is forthcoming. <br /> <br />Annual funding of the Agriculturdl Conservation Program practlces through the <br />Agricultural Stabilization and Conservation Service, for federal cost share <br />assistance in the valley during the past fe~ years, has averaged about $125.000. <br />The most common conservation practices installed under that level of funding <br />are ditch lining or pipelines, land leveling, and some closed drains. The <br />quantities and cost of conservation practices expected to he installed during <br />the next 10 years, assuming continuation of present levels of funding and cost <br />share rates, are tabulated below: <br /> <br />Practice Uni t Quantity Estimated Cost <br />Oi tch Lining ~i 58.0 S 1,824,000 <br />Pipeline Hi 4.5 136,000 <br />L.and Level ing Ac 600.0 212,000 <br />Closed Drains HI 2.5 128,000 <br />Total Cost S 2,300,000 <br /> <br />Presently, the salt loading from about 18 percent of the lrrigated area is not <br />SIgnificant, Continuation of the ongoing program is expected to bring another <br />2 percent of the area within acceptable limits duri~g the next ten years. <br /> <br />[nder Alternative Plan One a maximum salt load reduction of 10,000 tons per <br />year, a reduction of less than 3 percent, can be attained. Implementation <br />under the ongoing program could impact on 370 acres of wetland, or 1 percent <br />of wetlands in Lo~er GUnnlson Unit. <br /> <br />1\'-.') <br />
